Add YAML frontmatter to skill reference files

Add compliant YAML frontmatter to all reference files in anti-slop and
typed-holes-refactor skills to pass CI smoke tests. All reference files
now include name and description fields following Claude agent skills
best practices.

Files updated:
- anti-slop/references: text-patterns, code-patterns, design-patterns
- typed-holes-refactor/references: HOLE_TYPES, CONSTRAINT_RULES, VALIDATION_PATTERNS
